Abstract: The present disclosure relates to the field of communication technologies, and provide a near-field communication (NFC) chip, a phase synchronization method, and an electronic device, to quickly synchronize a transmitted signal of an NFC card device with a carrier of an NFC card reader. The NFC chip includes a processing circuit configured to: determine a first carrier frequency offset between a local clock signal and a carrier clock signal, and generate a first frequency control word based on the first carrier frequency offset. The carrier clock signal is determined based on a received signal received by the NFC chip. The NFC chip further includes a phase-locked loop configured to generate a first clock signal based on the local clock signal and the first frequency control word.

Abstract: Operation information corresponds to a first operation, where the operation information includes touch information and/or posture information of a terminal device, and manages the terminal device based on a matching degree between the operation information corresponding to the first operation and a first decision model, where the first decision model is determined based on operation information of an operation performed by a first user. According to a terminal device management method, because an operation of a user is habitual, a same user (namely, the first user) may generate a large quantity of similar operations in a process of operating the terminal device. Training is performed by using a plurality of operations of the first user, and a decision model is obtained. Based on the decision model, it can be determined whether an operation is performed by the first user.

Abstract: A data processing method and a terminal device, where the method includes obtaining a speed of the terminal device, receiving a first communications service, disabling a preset reminder of the first communications service when the speed of the terminal device exceeds a first preset value, and enabling the preset reminder of the first communications service when the speed of the terminal device decreases to a second preset value, where the second preset value is less than or equal to the first preset value. The data processing method and the terminal device are used for a user reminder of a terminal device in a vehicle mode.
